Oh my...do I ever remember that message!! I made both Earthenwear and SeaVue in Vue 4. It took me FOREVER to get them out because of that. I would make the mat using initial bmps and such and then when it was done, I converted all images to optimized jpgs, placed them in the appropriate spot and then created the path in the mat editor and saved the new mat. When loaded, Vue would still call out for the old discarded bmp time and time again regardless of the new path. I got to freakin' hate that message. You wouldn't believe how many times I had to recreate all those mats. And still.... Also in Vue 4, when a SeaVue mat was loaded, and Vue called out for a non existent bmp, I would guide it to the corresponding correct jpg and engage. When the scene came up, Vue had changed all the colors to maroons, reds and purples instead of blues and greens...wierd and very frustrating. What a relief when I got VI and it didn't happen. Frankly, I'm always leary to update. I always have troubles when I update stuff, from drivers to apps. So I'm stayin' put for now. If anyone who has my collections and is having troubles with this and you don't want to go to the trouble of resaving every mat, I do have 'saved in VI' versions I would gladly send you via WhaleMail. I had to do that for jje and his Mac version. I would just need your email addy. Never a dull moment eh? Render on! M
